Best Practices
This document holistically identifies the need for timely and reliable detection of hazardous gases as well as design of a leak tight SIP location:
This guidance document closes a significant gap in the understanding and use of SIP as a strategy for risk mitigation.
Foreword Excerpt:
For over 35 years, I have been conducting risk analysis studies on a range of facilities and transportation systems with flammable and toxic hazards. Having conducted hundreds of such analyses, I have evaluated a variety of risk mitigation systems and strategies to manage risks including complex mitigation systems to address hazards associated with highly toxic materials.
While Shelter-in-Place (SIP) has been a common mitigation strategy to mitigate public risk in the event of a toxic release from an operating facility, the use of SIP strategy for onsite personnel protection introduces additional complexities and considerations that should be accounted for in the strategy. However, in all the years I have been conducting risk analysis studies, I have found very few locations that have a good holistic approach to SIP. This became even more evident when, in discussions and deliberations during my participation on the Version 4 and Version 5 Committees to
develop API RP 751: Safe Operation of Hydrofluoric Acid Alkylation Units, I was unable to identify a single document that described a comprehensive approach to using SIP to mitigate toxic risk.

Mr. Gandhi is a member of BakerRisk’s Process Safety Group. He is a Process Safety Engineer with over 19 years of experience in controls and safety systems and over 12 years of experience in qualitative hazard and risk analysis. Mr. Gandhi manages Fire and Gas Systems (FGS) and Hazardous Area Classification (HAC) services at BakerRisk, where he has reviewed boilers and heater Burner Management Systems (BMS) to NFPA85 and NFPA86 standards.
Since 2020, he has led the Low Carbon Energy Risk Management group at BakerRisk which comprises of hydrogen and hydrogen carriers, biofuels, and Battery Energy Storage Systems (BESS) sub-groups. He has been a continuous member and leader of ISA at the student, local, and national levels since 2001 and the Hydrogen Technology Committee at CGA. He is the primary committee member for NFPA 715 Gas Detection Standard and is a contributing author on ISA TR84.00.07 Fire and Gas Detection and TR84.00.05 Burner Management System.
Mr. Sarrack is a member of BakerRisk’s Process Safety Group. His expertise is focused on process safety and risk analysis, where he has participated in hazard analysis teams, both as a contributor and as a team leader. His expertise also extends to the development of Fault Tree Analysis (FTA) and Event Tree Analysis (ETA), equipment reliability studies and failure data, and has executed source term and consequence analysis.
Mr. Sarrack has developed cost vs. benefit analyses for proposed facility modifications and provided technical risk analysis expertise to numerous plant decision processes. He has also produced risk management guidelines, as well as implemented procedures for performance of Facility Siting Studies (FSS) and Quantitative Risk Assessments (QRAs) for multiple companies.
Mr. Mather is a member of BakerRisk’s Process Safety Group, serving as senior principal consultant and Director of Process Safety. He has provided a wide variety of process safety and risk engineering services to oil, gas, chemical, and petrochemical companies around the world. Mr. Mather’s recent projects have included risk management services for LNG liquefaction facilities and regasification terminals; liquid and gas transportation pipeline systems; offshore well and processing platforms, FPSO’s; siting studies for refineries and chemical plants, and Quantitative Risk Assessments (QRA) for major oil and gas operations worldwide.

A dust explosion can be sudden and catastrophic, causing deaths, injuries, and destruction of entire buildings.
This BakerRisk Best Practice document provides general guidance for performing an FSS to ensure that the consequences or risks to people posed by facility operations are thoroughly, accurately, and defensibly quantified and allow consequences or risks to be minimized to the extent practical.
The objective of a HAC analysis is to minimize uncontrolled ignition by electrical equipment or hot surfaces of flammables in air that could lead to fires or explosions resulting in equipment and property damage as well as potential loss of life.
The HF Alkylation process is an important, core process in refinery operations to produce gasoline that meets modern clean fuels and engine performance requirements.
This document provides field tested suggestions and best practices to help bridge the gap between the standards and fire hazard studies.
